By Glen Whitney for the Museum of Mathematics We’re in the midst of putting four-bar linkages through their paces. See the introductory post for this series for the MoMath Linkage Kit, an introduction, and general instructions. Last time we saw the complexity of what seems like a pretty simple mechanism: four bars, connected at their […]
By Glen Whitney for the Museum of Mathematics A few weeks ago, I challenged readers to arrange six great circles so that every intersection of a pair of circles was equidistant from all of its nearest neighbors. If you’re still itching to try that challenge, best to do it before you read on in today’s […]
By Glen Whitney for the Museum of Mathematics Although Math Mondays has featured mathematical clothing before, it turns out there is an entire subgenre of clothing and accessories featuring those indivisible nuggets of the arithmetical world, the prime numbers. These range from the most basic, a list of prime numbers on the front (and composites […]
Learn how to make a torus model and then how to create a 7-color Ungar-Leech map on it.
By Glen Whitney for the Museum of Mathematics Before we leave the topic of Sierpinski Tetrahedra, with which many Math Mondays have been concerned, I wanted to highlight the story of one particularly impressive Sierpinski Tetrahedron which has indirectly inspired a host of young makers. Namely, it’s this record-setting order-seven “Rainbow Tetrahedron,” built in Cleveland […]
